Question

I have an xml file that has two links in it. I need to check to see if the link with the rel next exists if it does get the href value of it.

<a:link rel="prev" type="application/atom+xml" type="application/atom+xml" href="/v3.2/en-us/" />
<a:link rel="next" type="application/atom+xml" type="application/atom+xml" href="/v3.2/en-us/" />

Answer 1

How about reading the xml into an XDocument and using LINQ to find the next element.

XDocument x = XDocument.Parse("<xml><link rel=\"prev\" type=\"application/atom+xml\" href=\"/v3.2/en-us/\" /> <link rel=\"next\" type=\"application/atom+xml\" href=\"/v3.2/en-us/\" /></xml>");

XElement link = x.Descendants("link")
                 .FirstOrDefault(a => a.Attribute("rel").Value == "next");

String href = string.Empty;
if(link != null)
{
     href = link.Attribute("href").Value; 
}
